Severe dysphagia due to a huge epiphrenic diverticulum: long-term treatment with balloon dilation and botulinum toxin injection: a case report

We herein describe the first case of a high elderly patient with severe dysphagia in solids and liquids, caused by a huge epiphrenic diverticulum, who was treated with combined therapy of balloon dilation and botulinum toxin injection. Due to comorbid associated diseases the patient was unsuitable to withstand surgical or laparoscopic intervention. Treatment with botulinum toxin injection at the region of lower esophageal sphincter was unsuccessful. Combined therapy with balloon dilatation and botulinum toxin injection at the compressed part of esophageal lumen by the diverticulum resulted in improvement in dysphagia and malnutrition. During the long-term follow-up the patient developed symptomatic relapses, successfully treated by subsequent combined therapy resulting in longer-lasting symptom relief.
